Craig has been nothing short of amazing throughout the whole process. We’ve learned that we should definitely follow the protocol he outlines, and not the protocol that the remediation company wants to do! Save yourself time and frustration by just doing what Craig says :-)

Jennifer S. Troutdale, OR, 7/1/2025

Craig was very courteous, called to let us know in advance that he was running late. When he arrived he explained exactly what he would be doing and asked if we had questions. Upon completion of the inspection he explained the followup and told us what to expect next. Good experience all round.

John L. Portland, OR, 6/18/2025

Craig at Mold Inspection Sciences was SO wonderful to work with! I'd mixed up my calendar dates and had an outpatient surgery on the day of the appointment, and Craig was incredibly kind and understanding and helped make a plan so we could go forward with the inspection while I was recovering. He explained all the inspection findings clearly, let me know what the next steps would be, and helped everything run smoothly during a hectic time. I'd highly recommend Craig and MIS!

Craig was great! He was very thorough, professional, and explained the entire inspection process for us. Craig answered all of our questions and helped us understand all our options before our inspection, then did a great job with the actual inspection. The gentleman (Derek?) who made our appointment was very helpful, professional, and informative as well. We will get our report & samples within 3 business days, which was much faster than we anticipated.
I highly recommend Mold insp...

Craig was exceptional. He told us in detail what he would be doing, so we would know what to expect from the inspection. He then proceeded and was very thorough in his assessment of our entire home.

Mold Investigation Methods

Moisture Detection

Moisture Detection

Mold growth requires three things: mold spores, a food source (building materials), and moisture or water. So, where we find moisture, we find mold. By locating the source of moisture and identifying hidden water intrusions, we can focus our mold investigation in the right areas.

If there was water damage from a flood, a leak, or a natural event we can inspect and assess the water damage along with identifying the presence of mold and make recommendations on the best way to return the home or office to a healthy state. 

Infrared Technology

Infrared Technology

We use FLIR infrared camera technology to enhance our inspection services. This advanced, non-invasive technology allows our inspectors to zero in and identify potential sources of moisture to more accurately determine testing and sampling areas. This will allow us to make even more precise conclusions and recommendations for action during the inspection.

Sampling and Testing

Sampling and Testing

We often get questions about how we determine which sample types to recommend, why we recommended a specific number of samples, and other questions about our sampling approach - known as our Sampling Strategy. Through the course of the assessment, our inspector will put together a Sampling Strategy specific to your property that will allow us to pinpoint problem areas, determine overall contamination levels, guide remediation efforts when needed, or in other cases rule out mold as a source of concern. If you have questions about the type of samples used or are wonder how and why specific recommendations are made, you can find tons of information in our Sampling Guides. Feel free to reach out to us with specific questions.

Certified Mold Inspectors

Certified Mold Inspectors

Performing professional, high-quality inspections requires three things—certification, education, and experience—values we do not take for granted. Each of our inspectors, consultants, and project managers is a Certified Mold Inspector (MICRO and MIS CMI). To protect your liability, property, and health, it’s important to engage the services of a professional and certified mold inspector. 

No Conflict of Interest

No Conflict of Interest

We don’t perform mold remediation, repair, or construction. We have no interest in the outcome of our inspections other than to ensure you have the information needed to return your home or office to a healthy state. Our expertise guides us, and we never have a conflict of interest regarding our findings and recommendations. We use a science-based approach and only do inspections and testing, never remediation.
